I have had a little correspondence with Heiko Oberdiek 
(heiko.oberdiek@googlemail.com).  He is not an emacs user, but has said 
"If you get an answer that suggests an improvement in hyperref, let
me know."  I guess if anything is going to happen with this issue, it is 
up to someone who understands emacs well enough to illustrate the 
problem without actually using emacs.  He would be willing to take a 
look if the problem can be expressed in a way that does not involve 
emacs.  Here is an example

\documentclass{article}
%\usepackage{hyperref}
\begin{document}
\Nothing to see here folks.
\end{document}

Run latex from inside emacs and this will flag the "\Nothing" and 
position the cursor on that line.  Remove the % at the start of the 
second line, delete the *TeX Help buffer, do the same, and you will get 
"Error occured after last TeX file closed" and nothing else.
